The Mildred Andrews Boggess Memorial Organ is named in memory of the esteemed University of Oklahoma organ professor who, for thirty-eight years, dedicated her life to her students. A bequest from her estate provided the initial funds for this instrument, and her students contributed to raise the remaining funds needed.

The organ sits prominently on the second floor gallery in Gothic Hall, the lobby area of the Catlett Music Center. This airy, spacious, cathedral-like entrance to the Music Center has superbly resonant acoustics that are very agreeable to the organ.

Built in 1999 by C.B. Fisk, Inc. of Gloucester, Mass., Opus 111 is a three-manual and pedal organ that features 33 voices, 45 ranks, direct mechanical key-action, electric stop action and 128 levels of combination memory. The casework is of quartered white oak with mahogany accents that echo the steel truss work of Gothic Hall.
